Submitted the request on Feb 13, received the empty box on the 18th and dropped it off at FedEx that same day. I received a silver 6th gen on Feb 21.
Does anyone know if apple issues new serial numbers on refurbished units? I typed in the serial number on some apple s/n site and it said:
Build Year: - This unit was built in the first half of 2013.
Build Week - Week 5 (January) or week 32 (July)
It also looks like it's brand new with no scratches or marks anywhere on the device. It kinda leads me to believe it's brand new rather than refurb
